BOW-ANCHOR FOOT-PLATE AND SHIPPING APPARATUS THEREFOR.

Specification of Letters Patent.

Patented Aug. 2, 191@.

Application filed October 30, 1909. Serial No. 525,540.

To all whom it may concern:

Be it known that we, SYLVESTER GEORGE PERRY, of the town of Port Dalhousie, in the county of Lincoln, and CHARLES FREDnRroK STAFF, of the town of WVelland, in the county of Welland, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Bow-Anchor Foot- Plates and Shipping Apparatus Therefor, of which the following is the specification.

Our invention relates to improvements in bow anchor foot plates and shipping apparatus therefor, and the object of the invention is to provide a foot plate for how anchors which may be readily shipped and unshipped without any danger of the anchor sticking in the bed of the stream or lake when being raised and it consists essentially of a pair of leaf castings arranged at each side of the anchor point and abutting each other at their inner side, a detachably hinged connection between the leaf castings and the anchor point, and a shipping frame detachably secured on the scow or dredge for shipping the outer leaf of the foot plate as hereinafter more particularly explained by the following specification.

Figure 1, is a general perspective view of a bow anchor shown at the side of a portion of a dredge or scow with our foot plate and shipping apparatus connected thereto. Fig. 2, is a sectional plan View taken through the anchor point immediately above the foot plate. Fig. 3, is a vertical sectional view taken through Fig. 2 on line wy. Fig. 4, is a perspective detail view of the lower end of the anchor post. Fig. 5, is a perspective detail view of the anchor point and the leaves of the foot plate partially broken away and in section. Fig. 6, is a perspective detail of one of the leaves of the foot plate.

In the drawings like letters of reference indicate corresponding parts in each figure.

A is a portion of a dredge or scow.

B is the anchor post connected to the dredge or scow by the usual means, such means not being shown as it forms no part of our invention. The anchor post B is formed with a reduced portion B and a further reduced portion B arranged diagonally t0 the portion B.

C is the anchor point which fits onto the portions B and B of the anchor post, the portion B fitting between the internal bosses B formed in the anchor post shown particularly in Fig. 2 of the drawings.

D is the foot plate comprising leaves D and D each having hinge lugs D and D at their inner ends abutting each other as shown in Figs. 1 and 3.

It will be seen on referring to Fig. 6 that the hinge lugs D and D are arranged in pairs at each end of the plates D and D.

D" is a recess formed on the inner side of each of the plates D and D and in the center thereof.

D and D are pins which extend through the lugs D and D" toward the center of the plate and project slightly into the recesses D C are arc-shaped recesses formed in the anchor point C and designed to receive the pins D and D when the plates are in their operative position. The arc-shaped recesses U extend into each side of the anchor point and open out into the front and rear faces of such point. The upper edge of the entrance into the slots 0 are curved at C so as to allow of more ready entrance of the hinged pins D and D when the leaves of the foot plate D are being shipped.

F is a pulley secured to a cross arbor F provided with a suitable crank handle F F 3 are chains secured to the pulley F at their upper ends and detachably secured at the bottom to the leaf castings D and D of the foot plate D.

G is a shipping frame comprising horizontal arms Gr detachably secured to the deck of the scow by U-bolts G or other suitable means. The arms G are connected together by a cross plate G are depending arms hinged at their inner ends to the horizontal arms G and provided at their lower ends with inwardly curved portions extending to each side of the anchor point.

\Vhen it is desired to ship the outer leaf of the foot plate the frame is placed in the position shown in Fig. 1 of the drawing and the leaf D inserted between the anchor post and the frame at the top thereof and set in the position shown by dotted lines in Fig. l. The leaf D is provided with lugs 6 and 7 designed to bear against the inner opposing sides of the depending bars G so as to guide the plate D downwardly when lowered by means of the chain and pulley F and F respectively. The foot plate D is lowered in this position until the hinged pins D and D engage with the inwardly curved portions C of the arc-shaped recesses C.

By means of the curved portions C the hinge pins are guided into the slots C and also by means of the inwardly curved portions D of the shipping frame G. lVhen the ninge pins are brought within the slot the mot-ion of the crank F is reversed so as to pull upwardly upon the chain F and on the inner end of the foot plate also carrying the hinged pins upwardly into the top of the arc-shaped slots G into the position shown in Figs. 3 and To secure the hinge pins within the slots C I provide the following means:

H are a series of tubes extending downwardly through the anchor post to the boss B formed inside the anchor point.

I are holes extending through the bosses B into the arc-shaped slots C. These holes communicate at their upper ends with the tubes H.

1 orifices formed in the bottom portions of the arc-shaped slots immediately opposite the portion I hereinbefore re ferred to.

J are pins provided with pointed lower ends. The pins J are normally held within the orifices l in the position shown in Fig. 3.

J are cords extending upwardly through the tubes H. The cords are secured at their lower ends to the pins J and at their inner ends to rings J which are connected to fastening hooks J When the leaf casting D of the foot plate D has been brought into position hereinbefore described and as shown particularly in Fig 3 of the drawings we release the ring J from the hook J and allow the pin J to drop through the orifice I across the opening of the arc-shaped re cess G into the orifice 1 thereby closing the entrance to the recess. By this means the hinge pins D and D are securely held within the arc-shaped recesses which thereby form a hinge for the leaf of the foot plate. hen this has been accomplished we remove the frame G and ship the inside anchor. It will of course, be understood that no frame is necessary for shipping such inside anchor as the natural tendency of the hinge pins D and D thereof is to enter the recesses C when the leaf casting is being.

lowered.

K is the tackle by which the anchor post is raised the cable K of which extends over the pulley K mounted in suitable bearings on the deck of the scow. The cable then passes downwardly over the usual pulley journaled within the anchor post in the slot H whence the cable extends upwardly to a bracket K to which it is suitably connected.

Having described the principal parts involved in our invention we shall briefly describe the operation and utility of the same.

When it is necessary to raise the point all it is necessary to do is to operate the cable K in the usual. way so as to raise the anchor post vertically. As the anchor point C is withdrawn from the bed of the lake or stream the leaf castings D and D will fall into the position shown by dotted lines in Fig. 3 thereby allowing the anchor post to withdraw easily out of the mud forming the bed of the stream.

It will be understood by those skilled in the art that anchors hitherto have pins which extend through the anchor post in proximity to the bottom thereof. It will be seen that this cross pin will sink into the soft bed of the stream and make it very difficult to raise the anchor point out of the bed.

By our device it will be seen that as soon as the anchor point is raised the leaves will fall downwardly to each side of the anchor point and thereby allow of easy withdrawal of the post.

From this description it will be seen that we have devised a very simple means whereby an anchor post of a dredge or scow may be supported on the bed of the stream or lake without such support interfering with the easy withdrawal of the anchor post when it is being raised.
